摘　　要：制备了以石膏作载体、石蜡作相变材料的定形相变材料(复合石膏板)。实验证明表面活性剂硬脂酸钠可有效提高石膏板吸收石蜡的质量比,差示扫描量热结果显示复合定形相变材料中石蜡的相变温度、峰顶温度降低,相变吸热量与相变蜡在复合材料中的质量成正比。The figuration phase change material has been prepared with gypsum as supporting material and paraffin as phase change material （composite gypsum board）.The experiments prove that surface active agent sodium stearate can effectively improve mass absorption ratio of gypsum board to paraffin.The result of differential scanning calorimetry shows that transformation temperature,summit temperature reduce and heat absorption capacity of paraffin in composite figuration phase change material has direct proportion with mass of phase change paraffin in composite material.
